AERIAL FOR WIRELESS TELEGRAPHY AND TELEPHONY.

Specification of Letters Patent. Patented Aug. 22, 1911- Application filed October 9, 1908. Serial No. 457,012.

To all whom it may concern:

Be it known that we, WILLIAM E. D. STOKES, Jr., and GEORGE WV. Davis, citizens of the United States, residing at New York, in the county of New York and State of New York, and at Galilee, in the county of Monmouth and State of New Jersey, respectively, have invented a new and useful ony, of which the following is a specification.

The object of this invention is to provide a simple aerial and switching device so that the aerial can be quickly adjusted to receive the proper wave.

The device is illustrated in the accompanying drawing, in which- Figure l is a plan view of the adjusting or switching device; Fig. 2 is a side elevation of one of the switches; and. Fig. '3 is a front elevation of the construction of the aerial.

Referring to the drawing and in detail, A and B represent two posts, strung between which is a wire G which carries a number of vertical Wires D which are insulated from the rope or wire C by suitable insulators 10.

E designates a base-piece of insulating material, secured on which is a metallic bar ing device R, from which wires 12 and 13 of the receiving circuit are led. The base having-ears 14. As many posts G are provided as aerial wires D are employed, and each aerial wire D is connected to its own post G.

Pivoted to the metallic rod or bar F are knife switches S, each of which can be snapped down into the arms 14-14 of a post G. Byturning down as many switches S as desired, as many of the aerials D can be operatively connected to the wire 11 as desired, and the aerial can be quickly adjusted toreceive different waves, and a great many combinations obtained.

The details and arrangements herein copies of this patent may be obtained for five cents shown and described may be greatly varied by a skilled mechanic without departing from the scope of our invention as expressed in the claims.

Having thus fully described our inven tion, what we claim and desire to secure by Letters-Patent is-- 1. The combination in an aerial of two vertical points of-support, a wire between the same, a series of vertically arranged wires standing in a plane, and a switching device by which any of said aerial wires alone can be connected to the receiving circuit. v

2. In an aerial, the combination of two vertical points of's'upport, a wire or rope connecting the same, a plurality of vertically arranged wires depending therefrom and insulated from the supporting rope or wire, a switching device carrying'a number of knife switches, a plurality of posts having ears for said switches to engage a post being provided for and connected to each vertical wire of the aerial, and a receiving circuit connected to the switches, whereby the number of vertical wires operating in the aerial can be adjusted.

3. In an aerial, the combination of tw vertical masts, a rope or wire connecting the same, a plurality of vertical wires suspended. by said rope or wire and insulated therefrom, a switching device comprising a base, a metallic bar secured to said base, a post on said base for each vert-ical'wire, contact arms carried by said posts, knife switches arranged on the metallic rod or bar for engaging said posts, and a receiving cirset our hands, in the presence of two subscribing witnesses.
